This is a pretty good idea, actually. I think that it might take a lot out of the server if you have all those scripts, but the exhaust pipe and emitter (Kinda like on Phy's roadster) is a good idea, and engine sounds as well. Everything else I could do without, although they would be awesome. It would add a very nice ambiance to have engine sounds, especially in CityRP's and other forms of roleplay. Good idea, but I think that if someone were to do it they would have to set their priorities to what people would like the best and what wouldn't lag. I already have a feeling that skid marks might lag and exhaust animations might be a bit unnecessary, but all-in-all great idea.
Barnabas' vehicles are great when it comes to look and operation. What really gets me is the style of his cars, and I don't know if you've ever heard old cars running before, but if he added engine sounds to them then it would be amazing.
